NFPA 704 (fire diamond)
- Health (blue): 2 - intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury.
- Flammability (red): 1 - must be pre-heated before ignition can occur (based on organic components).
- Instability–reactivity (yellow): 0 - normally stable, even under fire exposure conditions.
- Special notice (white): - - no special hazards.

Protective measures
Gloves
- Nitrile: very good - chemical resistant protective gloves recommended for handling toxic components.
- Butyl rubber: very good - excellent protection against sodium hydroxide and toxic reagents.
- Natural latex or rubber: fair - adequate for brief contact but not recommended for extended use.
- PVC: fair - provides basic protection but limited chemical resistance.
Safety goggles
- Mandatory: Always wear safety glasses with side-shields when handling.
- Strong alkaline solution (pH 12.5) and toxic components require eye protection.
- Corrective glasses are not considered safety goggles.
- Part 1/2 may cause severe eye damage, Part 2/2 causes irritation.
Clothing
- Wear protective clothing to prevent skin contact.
- Long sleeves and full-length pants required.
- Closed-toe shoes mandatory.
- Remove and wash contaminated clothing before reuse.
- Caustic hazard: Part 1/2 contains sodium hydroxide which causes severe burns.
Respiratory protection
- Use only in well-ventilated areas.
- Toxic if inhaled - avoid breathing vapors from Part 2/2.
- Contact with acids liberates toxic gas - ensure proper ventilation.
- Use appropriate respiratory protection if ventilation is insufficient.
Spill management
- Use personal protective equipment including chemical resistant gloves and eye protection.
- Do not flush into surface water or sanitary sewer system.
- Soak up with inert absorbent material and dispose as hazardous waste.
- Part 2/2: Use mechanical handling equipment to avoid dust generation.
- Highly water contaminating - prevent environmental release.
- Never mix with acids - may generate toxic chlorine gas.
- Dispose according to waste code 160506 (hazardous laboratory chemicals).
Special warnings
- Two-part system - each part has different hazards and handling requirements.
- Part 1/2 (Sample cuvette): Contains sodium hydroxide (<0.2%), pH 12.5, causes severe burns (R35).
- Part 2/2 (DosiCapZip): Contains toxic sodium nitroprusside (12%) - toxic if swallowed (R25).
- Generates toxic gas - contact with acids liberates toxic gas (cyanide compounds).
- Aquatic toxicity: Very toxic to aquatic organisms with long-lasting effects.
- Storage: Keep in dry, cool place (2-8°C for refrigerated storage).
- Highly water contaminating class 3 - prevent release to environment.
- Chlorine generation: Part 2/2 may develop chlorine if mixed with acidic solutions.
- Professional use only - water analysis reagent for laboratory use.
- Disposal: Local Hach agencies will accept used cuvettes for proper disposal.
